Which statement best describes the compressibility of a gas? increasing the temperature of a gas decreases the pressure. increasing the temperature of a gas increases the pressure. increasing the pressure on a gas decreases the volume. increasing the pressure on a gas increases the volume.

Option (c) is the correct answer.

Explanation:

The ability of a substance to reduce in size or volume due to the increase in pressure is known as compressibility.

Also, according to ideal gas equation PV = nRT

where        P = pressure,                     V = Volume

                 n = number of moles,        R = gas constant

                 T = temperature

Since pressure is inversely proportional to volume. Hence, when pressure is increased then there will be decrease in volume. As a result, substance will be compressed.

Thus, we can conclude that the statement increasing the pressure on a gas decreases the volume, best describes the compressibility of a gas.

well in order to answer this question you have to provide more information < 3

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
